JAY DARLING, OF WILLIAMSPORT, INDIANA.

MOLD FOR CONCRETE POSTS.

To all whom it may concern:

Be it known that I, JAY DARLING, a citizen of the United States,residing at Williamsport, in the county of Warren and State of Indiana,have invented a new and useful Mold for Concrete Posts, of which thefollowing is a specification.

The object of my invention is to provide an improved post mold, in whicha wire fas tener may be positioned before the concrete is poured, andembedded in the concrete and readily removed with the post as it isremoved from the mold, whereby a considerable saving of time in makingthe posts may be effected; and to provide means for making a pluralityof posts, having the heads of the posts facing in opposite directions inthe mold; and to provide the novel combination and arrangement of partshereinafter set forth and claimed. I attain the objects of my inventionby the mechanism illustrated in the accompanying drawings, in whichFigure 1 is a top planof the invention;

Fig. 2 is a longitudinal vertical section on the line 22 of Fig. 1;

Fig. 3 is a transverse section on the line 33 of Fig. 1;

Fig. 4: is a perspective view of a completed P Fig. 5 is a perspectiveview of one of the mohl members detached from the frame; anc

Fig. 6 is a perspective view of one of my wire fasteners. v

Like characters of reference designate like parts in each of the severalviews.

Referring to the accompanying drawings,

I provide a frame for the mold members consisting of side frame members1 and end frame members 2, the members 1 also being connected byintermediate frame member 3. Attached to end frame members 2, I providemold supporting members 7 having U- shaped cut-out portions at toreceive the large end of the molds, and 4 to receive-the small end ofthe molds. I provide tapered molds 5, of U-shape in cross section andhaving out turned flanges 6. Molds 5 are provided with slots 8 andadjacent apertures 9, spaced at regular distances apart, as illustratedin Fig. 5, and adapted to receive the free end 11 and loop of the wirefasteners 12, as illustrated in Fig. 2. Intermediate frame member 3 isprovided with cut-out portions 4 of substantially uniform size tosupport the middle portions of the molds 5. The holes for the fastenerare punched in when the mold is made.

In operation the wire fasteners are first inserted through. the slots 8and apertures 9 of the molds 5, and then the concrete which may besuitably reinforced, is poured in the molds. When the concrete hashardened the set of postsfor siX are molded at a timeare removed fromthe molds, with the fasteners protruding as shown in Fig. 4. The siderails of the molds are preferably hinged in the center, for conveniencein shipping.

lVhat I claim is: I

1. In a molding apparatus for the molding of posts from plasticmaterial, the combination of a supporting frame, said frame including anintermediate frame member having cut out portions of substantiallyuniform size and the frame having a mold supporting member havingU-shaped cut out portions to receive the ends of molds, these cut-outportions being alternately of large size to receive the large end of themold and of-small size to receive the small end of the next adjacentmold, a plurality of reversely disposed tapered molds independentlysupported in and independently removable from the aforesaid supportingframe whereby any aarticular mold may be readily removed fordisconnecting the fastening device or distributing other molds.

2. In a molding apparatus for the molding of concrete posts of plasticmaterial, the

combination of a supporting frame, said frame including an intermediateframe member having cut out portions of substantially uniform size andthe frame having a mold supporting member having U-shaped cut outportions to receive the ends of molds, these out out portions beingalternately of large and small size to receive the end of the nextadjacent mold, a plurality of reversely disposed tapered moldsindependently supported in and independently removable from theaforesaid supporting frame, the supporting frame being made of hingedlyconnected sections, to permit of compact collapsing of the frame fortransportation when the molds are removed.

J AY DARLING.
